the charge-ordering state is in an alternate-charge-polarization phase (ACP: ···[Pt2+−Pt3+]−I0.4−−[Pt3+−Pt2+]···I0.3−···), which is consistent with a previous low-temperature X-ray diffraction study. The estimated valence states of the bridging iodines of [(C2H5)2NH2]4[Pt2(pop)4I] (pop = H2P2O52−), with a charge-polarization phase (CP: ···[Pt2+−Pt3+]−I0.4−···[Pt2+−Pt3+]−I0.4−···), and [H3N(CH2)6NH3]2[Pt2(pop)4I]
